目的 评估 Pentacam（Oculus，Wetzlar，德国）Scheimpflug 定量图像在评估晶状体密度方面的作用，并提供客观测量结果，以建议健康检查领域白内障手术的最佳时间。 方法 纳入 229 只患有年龄相关性白内障的眼睛。使用 Pentacam 测量镜片密度。所有 Pentacam 图像均导出至 ImageJ（NIH，贝塞斯达，马里兰州，美国）进行定量分析。计算平均晶状体密度（ALD）和核晶状体密度（NLD）。还通过内置 Pentacam Nucleus Staging (PNS) 软件评估晶状体密度。根据晶状体混浊分类系统 III (LOCS III)，使用裂隙灯显微镜对白内障进行分级。测量最佳矫正视力（BCVA）。所有测量值均在白内障手术组和非白内障手术组之间进行比较。 结果 Pentacam 图像的测量值与核乳光 (NO) 和核颜色 (NC) 分级的 LOCS III 显着相关 (p
Purpose To assess Pentacam (Oculus, Wetzlar, Germany) Scheimpflug quantitative images in evaluating lens density and providing objective measurements to suggest optimal time of cataract surgery in the field of health examination.Methods Two hundred and twenty-nine eyes with age-related cataract were enrolled. Lens density was measured using Pentacam. All Pentacam images were exported to ImageJ (NIH, Bethesda, Maryland, USA) for quantitative analysis. Average lens density (ALD) and nuclear lens density (NLD) were calculated. Lens density was also evaluated by built-in Pentacam Nucleus Staging (PNS) software. Slit-lamp microscopy was performed for cataract grading according to Lens Opacification Classification System III (LOCS III). The best-corrected visual acuity (BCVA) was measured. All measurements were compared between the cataract surgery and non-cataract surgery groups.Results The measurements of Pentacam images significantly correlated with LOCS III for nuclear opalescence (NO) and nuclear colour (NC) grading (p
